None of those 3 places are in Pedernales.
It's an OK place, been there often. It's a stop on our SW tours I've documented here. But I've yet to have any customer say "Wow! Pedernales! What a place!"
Excuse me, I understand we're talking about the Town of Pedernales, but those places I mentioned are in the province of Pedernales, as Boca Chica is said to belong to Santo Domingo and Punta Cana to Higuey, you wouldn't visit a town just because is a nice town, as I wouldn't visit Puerto Plata or Higuey just to visit... honestly I rather take HOT and DRY Pedernales than hot and ugly Puerto Plata anytime...
